Why Choose the 60-Layer Version?

The Purus International EnviroTack™ PM 3660 64 W delivers twice the usable life per mat compared to the standard 30-layer version — making it the preferred choice for high-traffic entry points where mats need to be changed frequently, or for facilities looking to reduce the frequency of mat replacement and the associated labor cost. The white color makes contamination highly visible, providing a clear at-a-glance indicator of when it’s time to peel to the next layer.

Like all Purus EnviroTack™ mats, the PM 3660 64 W incorporates renewable, plant-based Cardia BioHybrid™ material in the LDPE film, reducing CO₂ emissions compared to conventional petroleum-based mats. Used mats can be recycled in conventional plastic recycling streams.

Applications

• High-traffic cleanroom entry points where frequent mat changes are required
• Facilities looking to reduce mat replacement frequency and labor
• Cleanrooms: microelectronics, biotech, semiconductor, pharma production
• Pharmaceutical compounding (USP 797)
• Hospitals: operating environments, ICU centers
• Data centers, nuclear facilities, industrial workspaces

Frequently Asked Questions

What is the difference between the 30-layer and 60-layer versions?
The 60-layer version provides twice as many peel-off sheets per mat, doubling the usable life. The 60-layer film is slightly thinner at 1.4 mil / 35 μm vs. 1.8 mil / 45 μm for the 30-layer, but adhesive performance is equivalent.

Why choose white?
White makes contamination highly visible — dirt and debris show up clearly, making it easy to see when it’s time to peel to the next layer. Especially useful in high-traffic environments where mat condition needs frequent monitoring.

How many total sheets come in a case?
Each case contains 4 mats of 60 layers each, for a total of 240 peel-off sheets per case.

What colors are available in the 60-layer version?
The 60-layer series is available in Blue (PM 3660 64 B), White (PM 3660 64 W), and Gray (PM 3660 64 G).
